1 Claim.

This invention relates to a chock designed for use on a track rail forthe purpose of preventing cars from rolling out of positionaccidentally.

It is an object of the invention to provide a light but durable andemcient chock which can be readily locked to a rail so as to prevent itsremoval by unauthorized persons and which can also be easily carriedfrom place to place by the user.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claim, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

In the accompanying drawing the preferred form of the invention has beenshown.

In said drawing Figure 1 is a view partly in side elevation and partlyin section showing the chock in use.

Figure 2 is a section on line 2--2, Figure 1.

Figure 3 is a perspective view of the filler block and its wear plate.

Referring to the figures by characters of reference, I designates ablock formed preferably of hard wood and provided with a fiat base 2adapted to rest snugly upon the top of a rail R. The back end of thisblock has a short vertical face 3 while the front end is formed with anupwardly and forwardly inclined face 4. Another upwardly and forwardlyinclined face 5 is extended from the back face 3 and terminates at theupper end 35 of a concave front face 6 the lower end of which terminatesat the face 4.

The front face 6 has an arcuate wear plate I detachably secured theretoby screws 8 or the like and the curvature of this plate as well as of 40the corresponding face 6 of the block corresponds with the curvature ofthe tread of a wheel W to be held.

Block I is cased within a sheathing 9 of steel or other suitable sheetmetal, this sheathing being fitted snugly against the side face of theblock and also against the faces. 3, 4 and 5. The sheathing is held tothe block by bolts or rivets I 0 extending transversely therethrough.

Extending downwardly from the sides of the sheathing are integral wingsH adapted to engage the sides of the head of the rail. These wingsdiverge downwardly so as to straddle the base of the rail below whichthey extend as shown. The wings are so proportioned as to fit betweenadjoining ties T supporting rail R and both wings have openings l2adapted to receive a wedge l3. One end of this wedge can be connected toone 10 of the wings by a chain l4 while the other end is adapted to besecured by a lock l5 whereby withdrawal of the wedge is prevented.

A handle I6 is joined to the top of the sheathing as shown and by meansthereof the chock can 1 be conveniently carried from place to place bythe user.

When it is desired to place the chock in position the wedge I3 isremoved and the base 2 of the chock is placed on the rail while the wearplate I is placed against the tread of wheel W.

As the wings H straddle the rail R the wedge 13 can be inserted underthe rail and fastened to the two wings so as thus to prevent the chockfrom 25 being removed from the position in which it has been set.

It has been found in practice that a chock made as herein described isnot only light and easily carried but is quite strong and meets all ofthe requirements. Furthermore it can be locked quickly to the rail andby providing wings which extend between the ties, sliding of the chockalong a rail is prevented and unauthorized removal of the chock is alsoprevented.

What is claimed is:

A chock including a block having a base, upwardly and forwardly inclinedtop and bottom faces and a concave end face, an arcuate wear platesecured to the concave face for contact with 40 the tread of a wheel, ametal sheathing upon the side, top and bottom faces of the block, wingsintegral with the sheathing for straddling a rail and extending betweensupporting ties, and means detachably engaging the wings below the levelof a rail for detachably securing the chock to a rail.
